Common Questions — Immersion Heater Repair in Merton

Why is my immersion heater not working in Merton?

The two most common faults in Merton are a failed heating element (the water won't heat at all) and a tripped overheat thermostat (the safety cut-out has fired). We diagnose on arrival and carry both parts in stock for same-day repair.

How long does an immersion heater element replacement take in Merton?

An element replacement in a Merton property typically takes 1–2 hours — we drain down the cylinder, replace the element, refill, bleed air locks and run the heater to confirm recovery time. Some copper cylinders require the isolation valve to be replaced at the same time.

My immersion heater is on but the water is cold in Merton. Why?

If the immersion is powered but the water is cold in a Merton property, the element has usually failed or the thermostat is stuck in the off position. If the water is scalding hot and overflowing via the T&P relief valve, the thermostat is stuck open — both are same-day repairs.
